What's wrong with building sound insulation?

The poor sound insulation of houses is caused by many reasons, and many factors such as design, construction and sales will affect the sound insulation effect of houses. In the residential design stage, the requirements of sound insulation effect are often ignored because of the cost problem. In the construction process, in order to facilitate wiring, workers often set the sockets at the same position on both sides of the household wall, which undoubtedly makes the wall between the two sockets thinner, and the sound insulation and noise reduction effect of this part also decreases. Different materials used in the partition wall will also affect the sound insulation effect.
